Both objects are to be held in a lockbox at site ██. Because SCP-XXXX's properties are not relatively harmful, no special or unique containment procedures are required to contain them. Objects are to be removed only during testing.

Revision-B

SCP-XXXX is to be held in a soundproof cell at all times. Under no circumstances are the objects to be removed unless they are being provided a 'host'. Access to SCP-XXXX's chamber requires level 2 clearance or higher.

Description: SCP-XXXX consists of two objects, SCP-XXXX-A and XXXX-B. SCP-XXXX-A is a golden plastic comedy mask, and SCP-XXXX-B being a tragedy mask of the same color and material.
The anomalous properties of the objects manifest when two (2) individuals wearing the masks, are in close proximity to one another, and are able to make physical and visual contact with one another. When SCP-XXXX-A is activated, the wearers personality changes to joyful and nonchalant, Whereas SCP-XXXX-B causes the wearer to become melancholy and woeful. When both objects have been activated the two wearers will attempt to preform various comedic skits using various materialized props. The skits are mainly satire and spoof various forms of media, but have sometimes been observed as dark and tragic. In this case SCP-XXXX-A will attempt to make comedic and witty remarks to distract observers from the dark aspects of the skits. The masks will eventually fall off the subject after about one (1) hour, returning their normal personality as well.

Below is a list of sketches that subjects have preformed:

A parody of the 1979 film "Alien". Both XXXX-A and B flee from the alien and attempt to kill multiple times, each time failing miserably. The alien wounds XXXX-B. The final scene features XXXX-A who annoys the alien with puns, causing it to commit suicide.

A parody of the 2001 film "Harry potter and the sorcerers stone". The two yelled various 'spells' from the film while simultaneously pointing sticks at each other. The sticks produced jets of light varying in color upon speaking the words. The skit ended when XXXX-B shouted "Avada Kedavra" followed by a green jet of light hitting XXXX-A. The subject wearing it was found deceased, and the effects of XXXX-B deactivated.

A parody of the popular video game "Pokémon". SCP-XXXX-A and B shouted commands at two creatures of unknown species or genus, though one being vaguely reptile like. The two creatures used various unknown abilities to fight each other, Before XXXX-B was hit by a ball of flame from the reptile like creature. Subject was found deceased. Both creatures dematerialized, and the effects of XXXX-A deactivated.

SCP-XXXX-B proceeded to cry and mourn the loss of various people who died during the events of 9/11, while SCP-XXXX-A made various puns about planes and explosions.

Both subjects proceeded to mock various personnel. SCP-XXXX-A made various jokes about the objects contained within the foundation, while XXXX-B began crying and begging for SCP objects such as SCP-682 and SCP-173 to kill him. Subject even turned to one of the observers and begged for them to shoot him.

Addendum XXXX-A: SCP-XXXX-A and B emitted a loud screech on █/█/20██, effectively causing █ fatalities and ██ personnel to go deaf. This event occurred again on █/█/20██ and █/█/20██. Since then, Containment has been revised and class has been changed to Euclid. Study reveals that this is triggered when the objects are not supplied with a 'host' in twenty-four (24) hours. Why this property is just now being expressed is unknown.
